Recent Satellite Launches from Around the World

The big focus for space enthusiasts lately has been the remarkable mission of SpaceX's Dragon capsule to the ISS. While the station resupply effort went well, the secondary payload on the Falcon 9 rocket ended in failure. Due to a malfunctioning engine, other engines on the Falcon rocket overcompensated and burned longer than planned, resulting in the wrong orbital placement of the OrbComm satellite. Built by the Sierra Nevada Corporation, Orbcomm was an engineering test vehicle to help establish a new network of communication satellites. This example was a prototype, designed to test how the system would react in its orbital environment. There are 18 small satellites planned for the system, all due to be launched on Falcon 9 rockets. Unfortunately, the wrong orbit placement caused the Orbcomm to fail its mission and it de-orbited. NASA and SpaceX engineers are investigating the failure while company executives plan a way to continue this mission.

Meanwhile, there have been other launches around the world.
